Ammo Question/Tuner Question

Status
Not open for further replies.
Based on this test target, how many marks would you move at a time to get rid of the vertical in group 11? Each number on the target represents one mark, fwiw. Also, 10 was a repeatable sweet spot.

I just happened to tune a 24” BM today, based on my results, I would say two clicks to take the vertical out. My tuner is a Harrells that is 6.5 oz. I started at zero, at 13 it was a group that had vertical like your 11 and at 17 it had horizontal like your 9. 15 was the magic number, looks like your 10. Retested with two other lots with very similar results.
 
I'd sure like to hear more about this.

What is considered controlling....is it keeping recoil consistent?

Thanks
Jerry
I know you experienced it when shooting your Vudoo. If I recall you mentioned how you need to shoot it a certain way to get the best results.
But to elaborate further how fast or slow the rifle moves rearward affects the rate of how the barrel will move upward. Just like moving out on the tuner or adding weight it will speed up or slow down bullet/barrel exit timing.
Happy Nee Year by the way
Did you get your BR stock yet?

Thank you Sir!!

Not yet....Mr. Owens is hard at work and I patiently waiting.

Happy New Year to you as well !!
 
I've read all 6 pages on tuning but my question is where do you start? I'm going to the test center soon in Ohio. My thinking is you test without a tuner? Find the best ammo there and then tune? Assuming this is right then what tuner setting do you start with? I've read many start with the Purdy RX formula and then go from there.

Ideally, you test a tuned gun exactly as it would be shot in a match, which, by the way, is exactly what is suggested by the test center.

If you are new to the game then test without the tuner. The best ammo tested will still be the best ammo when you put a tuner on. It makes no difference how you tune or where you start, what counts is where you finish. You have 500 choices, use them all.

what he said

I use the Hopewell method to start the process though

like VLNBYR said start at 500 or start at 0 it makes no difference. Just keep bracketing it in until you get down to moving it in one click increments for the final polish

If my rifle wasn't tuned, I'd test without a tuner.

As far as where to start. Like others have mentioned 0 or 500 not sure it really matters. I started at 200 and went in and out from there no more than 5 clicks at a time to find my sweet spot.

Disclaimer...I'm new to this and other shooters posting here know way more than I do....I'm just having fun!!
 
If you are going to shoot with a tuner on, why test without one?
This is just my theory here but I think most will agree a tuner will not work a miracle on ammo that your rifle does not like so I look at the initial test as first finding ammo that the rifle likes then going back and polishing it up with the tuner. That may just be a habit carried over from my CF days but it seems to work for me. I guess starting with a random setting on the tuner or starting at 0 or 500 would work just as well but old habits die hard

These are just my thoughts....

If your rifle is already tuned I don't see a problem.

If not........Why complicate things with a tuner that's not set. I'd rather have a good base line with a bare barrel.

This is for me and my setup. My tuner turns very easy and I'm using a tube that has to be screwed on before shooting. Not sure I would trust the person at the test center to make sure my setting stayed in place. Not even sure it would be right of me to expect him to keep up with it either. I also think this would be different if the shooter was going in person.

I'd have no problem sending my rifle in without my tuner and my rifle is tuned. My understanding is the best ammo is still going to shoot the best either way.
